We are pleased to report that the Multi-Factor Authentication service is restored. Microsoft reported service restoration around 2:00 PM on Monday.
Microsoft provided additional guidance stating they would continue to monitor the situation closely. We’ve been doing the same and can confirm that the MFA is working. MFA challenges are working as expected, across all verification methods.
Thank you for your patience while we worked to resolve matters. Again, we apologize for the disruption. Please contact the Helpdesk if you have any outstanding issues or questions.
